The study looked at how different methods of activating pig embryos fertilized by ICSI affect their early development. They found that using chemical activation led to a higher rate of pronucleus formation compared to non-activated embryos. While the division rates were similar, the activated embryos had higher division rates. The blastocyst formation rates were also higher in the activated groups compared to the non-activated group. Overall, both activation methods were effective in helping pig embryos develop after being fertilized by ICSI.
